    Heat generated in the grinding process causes gypsum (CaSO4.2H2O) to lose water, forming bassanite (CaSO4.0.2-0.7H2O) or γ-anhydrite (CaSO4.~0.05H2O). The latter minerals are rapidly soluble, and about 2% of these in cement is needed to control tricalcium aluminatehydration. If more than this amount forms, crystallization of gypsum on their re-hydration causes "false set" a sudden thickening of the cement mix a few minutes after mixing, which thins out on re-mixing. H
